Install MySQL on Debian 12 Bookworm

In this guide, you will learn to Install MySQL LTS on Debian 12 Bookworm. MySQL is a Relational Database Management System (RDBMS). It is available in two editions:

• MySQL Community Server (Open Source).

Complete Guide To Install MySQL LTS on Debian 12 Bookworm

To complete this guide, you must have access to your server as a non-root user with sudo privileges. To do this, you can follow this guide on Initial Server Setup with Debian 12 Bookworm.

Step 1 – Download and Install MySQL Deb Package

At this point, you need to download the Latest MySQL Deb package from the MySQL Community Downloads page by using the wget command:

sudo wget https://dev.mysql.com/get/mysql-apt-config_0.8.25-1_all.deb

Then, you need to install the package with the following command:

sudo apt install ./mysql-apt-config_*_all.deb

Fix Error Debian Bookworm is not supported by MySQL

You will get the message that, Debian Bookworm is not supported by MySQL. So to install MySQL, we use the Debian bullseye repository. Select it and click OK.

Next, you need to select MySQL Server & Cluster, then press the TAB button to select OK and hit the Enter key.

Next, you need to choose the available version of MySQL on Debian 12, here in our case it was MySQL 8.0.

Again Select OK and then use the TAB  to move to OK and hit the Enter key.

This will automatically configure the latest Debian repository of the Database on your Debian 12.

Note: If you see an error like the following during the installation:

Download is performed unsandboxed as root as file '/root/mysql-apt-config_0.8.25-1_all.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)

Usually apt uses the user _apt to download packages. In this case, _apt doesn’t have to write permission and download the file as root. To resolve it, you need to make sure the package is writeable for user _apt:

sudo chown -Rv _apt:root /root/mysql-apt-config_0.8.25-1_all.deb
sudo chmod -Rv 700 /root/mysql-apt-config_0.8.25-1_all.deb

By running these commands, the error must be solved. To get more information, you can visit this guide on Fix APT Error Download is performed unsandboxed as root.

Note: If you want to add any additional tools using its repository or want to reconfigure it run the command below:

sudo dpkg-reconfigure mysql-apt-config

Step 2 – Install MySQL Server on Debian 12

Update your local package index with the following command:

sudo apt update

Then, install MySQL on Debian 12 with the following command:

sudo apt install mysql-server

You need to enter the password that you want to use with the MySQL server.

Then select the Strong authentication method.

Now proceed to the next step to start and enable your MySQL service on Debian 12.

Step 3 – Manage MySQL Service on Debian 12

At this point, you can start and enable your MySQL service on Debian 12 with the command below:

Step 4 – Secure MySQL installation on Debian 12

At this point, you secure your MySQL by running the MySQL secure script:

sudo mysql_secure_installation

You will be asked to enter the root password. Also, you will be asked to set a valid password component. And you will be asked if you want to change your root password. Answer them as you wish from there type y to continue.

Then, you can log in to your MySQL shell by using the command below:

sudo mysql -u root -p
